what to do when your Optoma projector no longer turns on

Reset the Optoma projector

When your Optoma video projector no longer turns on, first try to reset. This will remove any bugs related to the processor. For that, proceed as following :

  1. Unplug the power cable from the projector
  2. Disconnect all cables and peripherals connected to the projector
  3. Wait 2 minutes
  4. Reconnect the power cable
  5. Try to turn the device back on

If it turns on again, the procedure has worked. Reconnect the peripheral cables one by one to make sure that the problem is not with one of them.

If the projector does not turn back on, continue with the following troubleshooting steps.

Check the power supply

When your Optoma projector is no longer powered, it no longer turns on. If the lights are off or flashing, it is likely that a problem in the power supply circuit be the cause. Then carry out the following checks:

  1. Check that the connections are correctly made.
  2. Make sure that the cables are not damaged, stripped or melted.
  3. Check that the wall outlet is working. To do this, plug another device that works into the outlet. If it does not come back on, the outlet is defective and you will need to contact an electrician to repair it.

Check the general condition of the device

Poor maintenance of your Optoma projector may prevent it from turning on. Indeed, video projectors are relatively sensitive electronic devices that must be maintained to extend their lifespan. Then carry out the following checks and operations:

If your projector is dusty, or if you have never cleaned it, clean it. Indeed, despite the dust filters, over time some manage to infiltrate and can cause a failure of the device. Use suitable cleaning products such as a dry air canister. You can also consult the cleaning tips in the user manual for your Optoma projector model.

If your Defective Optoma projector has been impacted, dropped or oxidized, it is very likely that an internal component is defective. You can then try to open the device to check visually or with a multimeter the condition of the components. You have been warned! : risk of damage to the device. We do not recommend this manipulation if you have no skills in electronics.

Also check that your remote control is functional. In fact, your Optoma projector may no longer turn on just because the start control no longer works. To test it, all you need to do is start the device with the ON / OFF button. If in doubt about the functionality of the remote control, change the batteries.

Check that the Optoma projector is not overheating

When the Optoma projector turns on, turns off, then refuses to turn on, it is very likely that a overheating is responsible for the problem. Indeed, video projectors have a thermal sensor that causes the immediate and automatic shutdown when it detects a temperature that is too high for the device. This allows, among other things, to avoid damaging it. Several factors can be at the origin of the problem:

  • The ventilation is obstructed. Any objects must be kept at least 50 cm from the ventilation opening.
  • The fan no longer works. The latter allows the heat emitted by the processor to be evacuated. When it breaks down, the internal temperature then becomes too high and the safety mode is activated. As a result, the fan turns off during operation.
  • The environment does not allow the fan to be cool enough. Place your Optoma ventilator in a ventilated, shaded, dry place where the temperature is below 40 ° C.
  • The thermal sensor is defective. This being essential for the correct functioning of the video projector, when it breaks down, the device no longer works.

Optoma projector no longer turns on because of a defective part

When your Optoma projector still does not turn on after all of the checks previously seen, the problem most likely stems from adefective part. To verify this theory, it will then be necessary to carry out more technical manipulations.

optoma video projector does not turn on what to do

Check the status of the lamp

When your Optoma video projector no longer turns on and that the Lamp indicator lights up red, the problem stems from a lamp failure. The most fragile element of a video projector and having a very specific limited lifespan, it often happens to have to be replaced.

However, you should know that several problems can be at the origin of the failure:

  • the lamp connectors have burned out or are not plugged in properly
  • the bulb has burned out
  • the lamp is defective or has exceeded the usage counter
  • the lamp overheats and causes the device to switch off automatically
  • the color wheel is broken

Depending on the problem your lamp is having, you will need to either simply replace the bulb (in the event that only the bulb has burned out), either replace color wheel (if it is broken), either replace the entire lamp ie the frame + the bulb (in all other cases). You can do this relatively easily. In case you are not competent, you can call in a professional.

Discover the procedure for replace the bulb or the lamp of a video projector here.

Footnotes : If you have already replaced the lamp, check that you have reset the usage counter to 0. Indeed, this may prevent the Optoma projector from turning on if it has not been done.

Check the internal components of the Optoma projector

Finally, when your Optoma video projector no longer turns on, the fault may come from a faulty component : power supply board, motherboard, optocoupler, capacitor, fuse etc. are particularly fragile components. As a result, they wear out during use and eventually break down. Being essential for the device to function, their failure then causes its total shutdown.

When your Optoma projector no longer works due to a component, you will need to completely disassemble the device in order to access the power supply board. This is located on the back of the components. Once you have found it, then carry out the following checks:

  • Visually check the power supply board and its components for damage. In other words, check that they are not damaged, deformed, melted or burnt.
  • Check that the power supply board and each of its components are receiving voltage using a multimeter.
  • Pay special attention to the condition of the capacitors. They should not be bulging on the top as this is a sign that they are no longer working. You can also check their working condition with a multimeter.
  • Make sure the fuses have not blown by measuring their voltage with a multimeter or fuse tester.

You have been warned! : Risk of electric shock. Always unplug the device from the wall outlet before handling. Risk of damage to the video projector. We strongly advise against these manipulations if you do not have any expertise in electronics (disassembly, measurement, replacement, welding, reassembly). In this case, call a professional.
